1. (a) A collection system lift station must be equipped with a tested quick-connect mechanism or a transfer switch properly sized to connect to a portable generator, if not equipped with an onsite generator.
2. (b) Lift stations must include an audiovisual alarm system and the system must transmit all alarm conditions through use of an auto-dialer system, Supervisory Control and Data Acquisition system, or telemetering system connected to a continuously monitored location.
3. (c) An alarm system must self-activate for a power outage, pump failure, or a high wet well water level.

4. (d) A lift station constructed to pump raw wastewater must have service reliability based on:

   1. (1) Retention Capacity.

      1. (A) The retention capacity in a lift station's wet well and incoming gravity pipes must prevent discharges of untreated wastewater at the lift station or any point upstream for a period of time equal to the longest electrical outage recorded during the past 24 months, but not less than 20 minutes.
      2. (B) For calculation purposes, the outage period begins when a lift station pump finished its last normal cycle, excluding a standby pump.
   2. (2) On-Site Generators. A lift station may be provided emergency power by on-site, automatic electrical generators sized to operate the lift station at its firm pumping capacity or at the average daily flow, if the peak flow can be stored in the collection system.

   3. (3) Portable Generators and Pumps.

      1. (A) A lift station may use portable generators and pumps to guarantee service if the report includes:

         1. (i) the storage location of each generator and pump;
         2. (ii) the amount of time that will be needed to transport each generator or pump to a lift station;
         3. (iii) the number of lift stations for which each generator or pump is dedicated as a backup; and
         4. (iv) the type of routine maintenance and upkeep planned for each portable generator and pump to ensure that they will be operational when needed.
      2. (B) An operator that is knowledgeable in operation of the portable generators and pumps shall be on call 24 hours per day every day.
      3. (C) The size of a portable generator must handle the firm pumping capacity of the lift station.

5. (e) Spill Containment Structures.

   1. (1) The use of a spill containment structure as a sole means of providing service reliability is prohibited.
   2. (2) A lift station may use a spill containment structure in addition to one of the service reliability options detailed in this in subsection (a) of this section.
   3. (3) The report must include a detailed management plan for cleaning and maintaining each spill containment structure.
   4. (4) A spill containment structure must have a locked gate and be surrounded an intruder resistant fence that is 6.0 feet high chain link, masonry, or board fence with at least three strands of barbed wire or 8.0 feet high chain link, masonry, or board fence with at least one strand of barbed wire.
6. (f) A lift station must be fully accessible during a 25-year 24-hour rainfall event.
7. (g) Lift station system controls must prevent over-pumping upon resumption of normal power after a power failure. Backup or standby units must be electrically interlocked to prevent operation at the same time that other lift stations pumps are operating only on the resumption of normal power after a power failure.
